Joule Thief

[gadgetmall]

hi all



I was thinking, we could use a transparent plastic tube with water in it, and put some luminescent
powder in the water, then use one (or more) UV LEDs to make the powder glow brightly... ?
Sort of like the poor mans DIY fluorescent tube, but instead of a phosphorescent coating
on the inside of the tube we use "glow-in-the-dark" powder and instead of pulse ionising
a mercury vapour that feeds energy to the phosphorescent material, we'd simply use our
JT-powered LEDs...
Ok, I admit I have not considered absorption of the UV by the water nor related ionisation
effects, but I do have a little of such glow powder hidden away somewhere and I also have
a couple of UV LEDs (somewhere around here) so I think I may just try it sometime soon.

You also said, in a later post:
Now I've only toyed with my 3 modified camera citcuit "Joule Thief"s so far, lit various numbers and types
of LEDs as well as fluorescent tubes, but have not built one from scratch yet (still awaiting my ring cores,
thinking of cannibalising an old and quite large transformer from an old switchboard now, it's just taking too long)...
... but my camera circuits only have one transformer on them...
And the pics I saw of the camera circuits on Jose's website as well as the pics I've seen from others also show
the same circuit and pcb as I have, with one transformer on it.

What camera board are you referring to that has two of them?
Or are you perhaps talking about using two camera board in tandem??

By the way, that's one freaky looking coil ring setup you pulled from those vcrs!
Can you use it in the same way as the ring of JTs you posted like 20 pages ago?

What a Brilliant IDEA koen1 . your Hear that Pirate . That is perfect ! . I got a Batch of Uv leds too . if you shine them on pink it gives off white light ..

@all
Im out of here and History Because I am Broke I will sell any dam thing i want to where i want to and  when i want .

there 2 transformers in every cam unit ... as i have seen

the second is the little one that goes to the flash...

I'll attach a pic of a typical "mod cam JT" board, I've circled a component in red,
is this the component you're talking about? Or is it the small square thingy next to it perhaps?
Since the part I circled only has 2 connectors I did not think it to be a trafo,
and the square thingy next to it is depicted as a capacitor on most schematics,
so I don't think that's it, is it?
Is that second trafo on my pic at all?
If so, please! do point it out, because now I'm wondering where this second trafo is.
Or maybe we're just talking about different camera boards althogether?

(sorry for the questions)

so you dont think i can top the fugi with a homemade jt... 

No, I never said that and neither do I think so. The camera circuit is just a
circuit, I'm pretty sure you (or anyone) could build a similar circuit that
functions as a much better JT than the camera circuit. I never claimed otherwise.
I merely stated that I have so far only played around with the modded camera boards
because I have not got workable sized ring cores yet. I have some, but they are way
too small to wind a decent number of windings on, what with the wire diameter and
the big fingers I've got

i know this is wrong ...

AS THE FUGI IS BUILT WRONG 

Well, yeah, duh, it was never designed nor intended to be a JT, it was meant to just make
the camera flash work. For that, it did the job.
And it just so happens that when you rip half the components off the pcb, you're left with
a small circuit that resembles the JT circuit to such a degree that you can perform JT-like
tricks with it such as lighting LEDs and CFTs.
But of course it is not a properly designed JT!

I HAVE SAID THIS LONG TIME AGO ... IT NEEDS TO BE TUNED ....  MORE THAN JUST CAP RES AND COIL ...

Okay okay, no need to SHOUT buddy
I don't think that's something we should focus on, tuning the camera circuit. I think the camera circuit is a nice plaything,
but if we really want to make proper JTs, we're better off building one of our (your?) own design and from loose components,
and not by ripping the unneeded components off a cheap camera circuit and hoping for the best.
That's why I like to read about the schematics posted by our more electrotechnically inclined friends here,
so that when I finally get down to building a JT from scratch, I can at least take advantage of the insights
thus shared already.

but walk the path you  have choosen

you say that as if I have just declared the camera circuits holy doctrine and the true JT a heresy or something
Not sure I've chosen a path at all really, I'm still planning to build a JT and still keeping up with the thread,
and I certainly don't favour the cam mod over the JT proper. Make no mistake.

How's about those crystals, by the way?

Oh, and when you mentioned "Kymatica", did you mean "Cymatics"?

Kind regards,
Koen

well

about the fugi being built wrong .....  it is because it is not designed to harness big kicks... ...  my mot APEARS TO BE WIRED CORRECTLY



because in 1 pulse i can put 130v in  2 caps 370vac motor run caps... 60uf

1 push of the button .... now that is a tuned transformer wired to recover and compound flyback

with HUGE OUT PUT   OVERUNITY .... ELECTRICAL OUT PUT DUHHHHHHH!!!!!!!   NO WAY LOL

my investor was tooo BLIND TO SEE THIS DEVICE IN FRONT OF HIS EYES....  LOL

or understand HOW AND WHY IT WORKS  EVEN WHEN TOLD HOW .....   SHEESH


THE HELL WITH INVESTORS ...   they all are about money WICH IS FAKE!!!!!!!!!!!!   LOL

IM ABOUT WHAT I HAVE LEARNED AND CONTINUE TO LEARN

AND WHAT I CHOOSE TO SHARE WHEN I CHOOSE TO SHARE IT ....

for get the crystals for now ....  lol   

i have had mine close to 2 years now ....   i have not opened the bag.... 

it is best to learn WHAT YOU TOY WITH FIRST


IST!


@keon1       verry nice responce .....  to the "Kymatica", did you mean "Cymatics"?   lol

@all

These are ceramic capacitors.
